Fatal System Errors (F9xxx and E-xxxx)
In the case of fatal system errors there is a grave problem in the drive
system (e.g. watchdog error, processor crash, ...) which does no longer
allow regular operation of the drive. Due to a hardware or firmware error,
the drive firmware is no longer operable; clearing an error is no longer
possible.
In this case the drive reacts automatically as follows:
• All digital outputs are set to "0".
Safety technology: safety related feedback is deactivated!
• The "ready for operation" relay opens, this also switches power off in
case the wiring is correct.
• The output stage is locked, this disables the drive torque.
• The brake output is deactivated; if a self-holding brake is used, it is
applied!
• One of the following diagnostic messages is output at the display:
• F9xxx (fatal system errors),
• E8xxx (exceptions),
• or E-xxxx (processor error), e.g. E-0800 (detailed information in the
English language is output via the serial interface).
After a fatal system error has occurred, the drive can only be put into
operation again when:
1. the 24 V supply is completely switched off and on so that a restart of
the drive is carried out (incl. booting process and initialization).
2. the drive is run up to the operating mode again.
3. power is switched on again.
Note: In case fatal system errors are occurring repeatedly, contact
our service department as operating the drive then is no
longer possible.
8.2 Recommended Actions for Operating States, Activities
and Reactions of the Drive Controller
The following table lists operating states, activities and reactions of the
drive controller. If an error, for example, occurs during operation, take the
actions in the given order until the error has been limited / cleared.
